globe and support to be moved readily from place to place; yet anotherfeature of this invention is that the support may be moved with verylittle physical effort; other features and advantages of this inventionwill be apparent from the following specification and drawings, in whichFigure 1 illustrates the globe and support being moved; Fig. 2 is adetailed sectional view of the socket; Fig. 3 is a view of the basealong the line 3 of Fig. 1; Fig. 4 is a view of another embodiment ofthis invention; Fig. 5 is a view along the line 5 of Fig. 4; and Fig. 6is a sectional view on the line 6 of 4.

It has been quite common to mount globes in supports having a baseadapted to stand upon the floor of the room in which the globe is beingused. In order to provide a firm support, however, it is necessary thatthe base have a large diameter. This is generally achieved by having abase which com rises three or more legs extending outwardly from thecentral support. The entire assembly is usually rather heavy andcumbersome, and thus difficult for a teacher or pupil, for example, tomove from place to place in the room, or even to another room. Castershave been used on the bases in order to assist in movement. Suchcasters, however, become rusted or stuck in one position after longdisuse, and thus prevent easy guiding of the support when it is beingmoved. Such casters, moreover, are of small diameter, and thus are verydiflicult to move over along slight projection in the floor, as athreshold or the edge of a rug.

This invention provides a globe support and base which obviate thesedifficulties. The base member is made in the form of a wheel, and is ofsuflicient weight and diameter not only to serve as a firm base, butalso to act as a counterweight when the support is inclined from thevertical position. The base, or wheel member, is also provided with aperipheral traction member or the which prevents the base from slippingout from under the support when the support is inclined. It will bereadily apparent that when the sup port is inclined, the base serves asa wheel member and counterweight, permitting ready movement from placeto place with little physical effort and with no interference fromintervening projections above the floor level.

In the particular embodiment of this invention illustrated in Figs. 1, 2and 3, the base wheel memher is. indicated by the reference numeral It.The base member has centrally mounted therein, and perpendicularthereto, a support or standard 5 H, here shownas a pipe or tube. Thesupport receives therein an extension member or rod I2, which extensionmember may be locked at any desired point, as by the wing nut IS. Theextension member has mounted thereon a socket 10 [4, which socket isformed integral with the yoke 5.- The yok has. th U- p upp r n members86 which yieldingly engage an annulus H, which annulus has, a globe l 8mounted therein on its polar axis 19,. The reference numeral 2o ndicatesa person in the act of moving the globe and.- support, showing the hand2! grasping the annulus and the hand 22 grasping the yoke of thesupport.

Referring more particularly to Fig. 2, the socket I4 is shown as havinga recess or opening 23'which receives the extension member l2. Theextension member l2 has near the upper end thereofa. circumferentialrecess or slot 26, which slot is adapted. to receive the end of aplunger 25. 5 The plunger is yieldingly mounted in a housing 26;,whichhousing is mounted in the socket M, and has an exterior handleportion 27. The construction of the socket forms a firm support andconnection between the yoke and the extension 30 member, and yetpermits. ready rotation of the one with respect. to the other. When itis desired to disassemble the support, the socket may be removed fromthe extension member by pulling out the handleportion 2'! sufficientlyto disengage the plunger 25. from the slot 2v Referring moreparticularly to Fig. 3, the base member ID is shown downwardly turnedtowards its edge 28. The member is provided, near its edge, withdepressions or grooves 29 and 30, 0 which grooves are adapted to receivethe ends ofv a. split tube or tire 3!. The base l0 may be of any desiredheavy material as iron, which material is prevented from contacting thefloor by the frictional member or tire 3 I. It will be noted 4 that thetire 3| is so arranged as to engage the floor in whatever position thebase member l0 may be.

Due to its diameter and weight, the wheel member 10 forms a substantialbase for the support H and maintains the globe and support in an uprightposition during normal usage. When it is desired to move the globe, theentire support is inclined from the vertical, substantially asillustrated in Fig. 1. The member It] now serves is an elevated one;

a dual function, serving as a counterweight to balance the weight of theglobe and yoke, and as a wheel adapted to roll along the floor when aforward force is applied by the person 20. The

.frictional member 3i prevents slipping of the wheel member It, andinsures that it will follow the forward course desired by the personmoving the globe. In the embodiment illustrated here,

the rotation point between the globe and the wheel member is at theconnection between the extension member I2 and the socket M. It may bethus seen that the globe, annulus or yoke may be grasped when the globeis being moved, since all of these parts may be held while the wheelmember, support and extension rod rotate with respect thereto.

In the embodiment of this invention illustrated in Figs. 4, 5 and 6, thesupport I and the extension member l2 do not rotate with respect to theyoke I5 and globe it. The standard II is here shoWn as provided with ahandle32 which may be grasped. by the hand'22 when the globe and supportare being moved. The base member I5 is, in this embodiment, rotatablymounted with respect to the standard II. This may be accomplished, forexample, by providing the base member It with an opening 33 adapted toslidably receive the support I l and by mounting col- .lars 3d and 35upon the support ll above and below the opening 33.

In this embodim nt the base I 9 is illustrated as having at its edge arim or socket 3B, which socket is substantially semi-circular in crosssection. This socket is adapted to receive a frictional member or rubbertire 3'! having therein a tension member or wire 38, which tensionmember holds the tire in place in the socket. It will be noted that theedge 39 of the socket does not touch the floor when the base is in itsnormal position, and that the exterior edge 49 is sufficiently removedfrom the floor not to contact the same even when the base is inclined ata considerable angle.

It will be thus seen that the tire 31, like that illustrated in Fig. 3,forms a frictional contact with'the floor in any desired position of thebase member l9.

The standard of'the support disclosed herein That is, it reachessubstantially to, or higher than, the waist of anormal adult, so thatwhen the base of the support is resting on the floor, the globe may beconveniently examined without sitting down or stooping. The base,standard, yoke and annulus are preferably made of metal and thus theentire combination is too heavy to be conveniently picked up and'carriedwhen it is desired to move it from modiments of my invention, it is tobe understood that it is capable of many modifications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claims, in which it is my intention to claim all noveltyinherent in my invention as broadly as permissible, in View of the priorart.

What I claim as new, and desire to secure by, Letters Patent, is:
